> During employment with VerticalNet, Park served on the XTM Authoring
> Committee which created the XTM topic maps specification, now a part of
> the ISO 13250 Topic Maps standard. In a former life, while serving as
> the president of the American Wind Energy Association, Park was
> constructing microprocessor-based weather stations used for siting wind
> energy farms and in agricultural applications. The massive amounts of
> data being collected by those stations led to investigations into AI
> applications in data mining and data organization. Ontologies and
> inference engines naturally followed. Park has crafted Java-based
> inference engines for a large banking enterprise, a clinical informatics
> enterprise, and participated in the construction of the VerticalNet B2B
> ontology editor. Park authored _The Wind Power Book_ in 1981, and
> co-authored and edited _XML Topic Maps: Creating and Using Topic Maps

> renewable energy resources in the U.S., and lectured on those subjects
> in the U.S., parts of Europe and Africa. He spends most of his time now

> call for continuous improvement of human capabilities. (011)
